The experiment consisted of 16 treatment combinations with four replications. The treatments include 4 levels of irrigation, viz., 100%, 80% and 60% ET through drip and flood irrigation; and 4 levels of fertilizer application, viz., 100%, 80% and 60% recommended NPK through fertigation and 100% recommended NPK as manual application. Flood irrigation and manual fertilizer application were treated as control. Drip irrigation and fertigation recorded the significant influence on growth and yield attributes of cucumber hybrid SH-CH-1. Among irrigation levels, the maximum values for plant height (7.97 cm), number of branches per plant (4.39), number of nodes per main stem (33.4), total number of fruits per plot (347.18), fruit weight per plot (115.89 kg) and yield (1340.8 q/ha) were recorded with 80% ET through drip (I₂). However, among various levels of fertigation, the treatment 80% recommended NPK through fertigation (F₂) produced maximum plant height (7.89 cm), number of branches per plant (4.35), number of nodes per main stem (33.2), number of fruits per plot (355.81), total fruit weight per plot (117.63 kg) and yield (1360.9 q/ha). It was further observed that the combined effect of drip irrigation and fertigation proved significantly superior over their individual effects. The treatment combination of 80% ET through drip + 80% recommended NPK through fertigation (I₂F₂) produced maximum yield (1444.10 q/ha) which was found 68.1% more yield than the traditional method of irrigation and fertilizer application besides saving of 37.8% water and 20.0% fertilizers and noticed highest B/C ratio (5.99:1) with net seasonal income of Rs. 6,18,770/- as against Rs. 3,42,181/- realized per hectare under traditional methods for one cropping season.
